I saw it somewhere between 15-20 years ago. On tv it was color and seemed modern for the time. (So maybe 90ish setting and release)
From what I remember of the plot there was a guy and a girl who liked each other but for some reason weren’t allowed to be together. I think her father had placed a restraining order on him or something. I believe the guy was under house arrest.
I remember 2 scenes. One was the girls father and his friend checking the mattresses with a black light to prove that the couple had had sex again.
And the guy getting his mail and having a bunch of fan letter type mail and one was an envelope full of photos of a girl undressing herself. ( I kinda remember someone walking in on him looking through the photos and him dropping them)
